Getting the real height for a modal window

Ever used a modal window? I know that I have.
One of the main problems with it, that when you open it, the background element does not fill the entire document, but only the visible area. For this reason we use a function that gives us the entire scrolling height of the body/documentElement.

//----------------------------------------------------
// getScrollHeight
// return - entire document height
//----------------------------------------------------
function getScrollHeight() {
   var d = document.body;
   var de = document.documentElement;

   return Math.max(d.scrollHeight,
                          de.scrollHeight,
                          d.offsetHeight,
                          de.offsetHeight,
                          d.clientHeight,
                          de.clientHeight
   );
}

To use it in a script just write something like:
document.getElementById('modalWindow').style.height = getScrollHeight() + 'px';

Word 2007

Well well well….

Apparently you can post directly from word 2007. It took me only 5000 years to find it!

So now that I know this small and unimportant issue I'll post more frequently.

Cheers for now.
